A CORPORATION OF a FILLING-GATGHER ron LOO lush 7 1T0 aZZ whom it mayconcern Be it known that I, MELVIN L; swim,

a? citizen of the. United. States, residin at Lawrence, in the countyofEssex and tate of 'Massachusetts, have invented an Improvement inFilling-Catchers for Looms,of which the following description, inconnection with the; accompanying drawings, is a specification, likecharacters on the drawings representing like parts. a

This invention relates to filling replenishinglooms, and moreparticularly toa filling or thread catcher for removing the old fillingfrom the loom when the fillinghas been replenished. I w v I In looms ofthis general type, when the filling in the shuttle isreplenished,thepiece of old filling or that extending from thesubstantially-exhausted filling carrier is caught or parted between thecloth selvage and the shuttle-box,andthe two ends of the parted fillingare moved frontwardly of the loom. At such time the frontward movementof the clamp which holds the ends of the filling,

will draw the filling from. the shuttle box either entirely; or partly,and will stretch the filling end leadingfrom the cloth selvagediagonally'toward the front of the loom;

One of the important features of-the present invention is to dispose ofthe piece of filling which extends between the thread parterand clamp tothe cloth selvage after a replenishing operation, and the. action of thethread parter and clamp.v This feature of the invention is carriedinto-eflect by a yielding thread catcher which, when the thread parterand clamp have performed their parting and clamping functions and havebeen moved frontwardly, rests upon the piece of filling extendingbetween the thread parter and clamp and the cloth selvage, and actsimpulsively to throw this piece of filling out of the loom when thefilling is parted or cut bythe usual temple thread cutter at the clothselvage.

Application ti led May 27;

Thel loom frame hasl secured jtliereto bracket 1- which; aflordsajsuitablefsupport' for the shuttle 'feeler 2-fwhich maybe ofusualconstruction. In'the Y the shuttle 'feeler 2 base hub jportion 3through which passes the 'pinf l which afpresent instance fords asuitable rocking support for the shuttle feeler. The shuttle feeler isnormally held in its front positionor' toward the breast beamof theloom,andis moved rearwardly to feeljfor the shuttle and to part and clampqthefilling thread between the cloth selvage and shuttle only on call forreplenishment of filling. This general construction and operation is ofusual character in this class of looms, and recently it, has beenproposed to glve the shuttle feeler' and the thread parting and clampingdevices which are usually mounted on it, aside or lateral movement asthe shuttle feeler moves from its rearward feeling to its 'frontward oridle position, in orderto prevent breakage er the filling thread'. whichis held by the clamp and leads fromthe cloth s elvage, In the presentinstance, the shuttle feeler is shown as of the type wherein the lateralY movement is given tothe'shuttle 'feeler', but

- theinvention isappli'cable to either this type or-that in which theshuttle feeler has only a movement toward and fromthe' frontgf theloom.1.

The shuttle sea 2' "has the a usual diver-g 1 ing or beveled-endportionsto feel for or' contact with the shuttle and toguidefthe fillingthread" into, position to fbe cut .or parted by the threadrpartingdevice's. In the present instance ofithe invention, the rear endportion-of the, shuttle feeler 2 has the upper inclined feeler end5"'and the lower inclined feeling end 6 whiclnas the position, willdirect thethi'ead, as usual, into the thread-partingposition. The endpore tions' 5' and 60f the shuttle feeler have a slot i Tbetween them,-into which the thread is guided to the parting: devices. a

'- .'Mounted 1on theishuttle'fifeeler' 2' is 95 shuttle feeler movesrearwardlyto feeling 9( These maybe of usualfconstruction and mayoperate in any approved mannerto part the filling when the shuttlefeelerfaiid.

'parter are :in their rearwardor operative pov 10 tending therefrom,

to be engaged by -the lay or a part carried thereon when the shuttlefeeler and thread parter are in their rearward operative, posi-v tion,as usual. The partlcular constructlon zofthe thread'parteris not of theessence of the present invention, andthe character of parter thus fardescribed is one" which is well known inthe art. The end portion 11 ofthe movable "parting member 9 has a pin 13 exwhich .is adapted to engagean opening member 14 (Fig. 1) to open .the thread parter when thes'huttlefeeler and "parter are moved toward their rearward or operativeposition, The opening member 14: is preferably mounted on a fixedsupport 15 and is connected to the support for rocking movement in onedirection 'or frontwardly, in the present instance, to permit the threadparter topass. fromits rearward to its front position as the shuttlefeeler moves cfrontwardly without. opening the parter or clamps and toeffect opening ofv the parting members .8 and 9 when the. shuttle feelermoves rearwardly to its operative position. These parts may all be ofusual character." The support 15 in the present instance of theinvention, is shown as clamped at16 to the bracket 1, l r In weavingcertain kinds of fabrics, for instance, such as duck or other fabricswhich use a relatively heavy or strong filling thread, it-is desirablethat the filling thread leading from the cloth selvage after theoperation of the, parter, may be securely clamped so vthat as the parterand shuttle feelermove-frontwardl-y, the filling leading from the clothselvage will not be pulled from the clamp. The present inventiontherefore provides a thread clamp of novel construction and which ismore especially adapted for use in weaving heavy goods, such as duck. V

. The lower member of the clamp is preferably formed as part of thelower end member 6 of the shuttlefeeler, or it may be secured theretoand project laterally therefrom as indicated at 17, Fig-.- 1. The threadengaging surface of the lower member of the clamp has a seriesof ribs orcorrugations extending transversely thereof, which do not interfere withthe proper guidance of the fillingvthread to the pa-rter when theshuttle feeler and; parteriare moved to their rearward fillingengagingposition. V

t-The other member of the thread comprises thefmember 19 whichis'preferably coextensive with the radially-extending lower member 17indicated in 1.' The upper clamping member 19, is similarly providedwith alternate ribs and corrugations 20 alternating with those of theopposed clamping member 17. The two clamping members formaneXtendedIcla-mping surface which clamp projects laterally from theparts which carry them, and affords a secure clamp for 1 holdingeve-nqthe heaviest character of yarn.

The upper clamping member 19 is formed on or secured to an arm which ismounted .on and-:movable with the movable thread parter. In thepresentinstance, the arm comprises a part 21, Figs. 1 and 2,which;.isbolted or secured to the movable member 9 ofthe thread parter at 22. Thearm 21 is preferably formed to provide a yielding ac: tionfor theclamping members17 and'19. In the present instance the arm 21haspivotally mounted thereon at 23, the clampcarrying arm 24; to which theupper clamp 19 is secured, or with which it may be formed integral. Asprlng 25 normally tends to move the arm 24 toward the'clampingposition, but yields upwardlyand is restrained from effecting movementof the arm to clamping position by means of a stop 26 on the arm 21. anda cooperating stop 27 on the arm 2%. The spring 25 maybe appropriatelysecured at 28 to thea'rm 21 and have its end portion 29 embracingtheupper portion of the arm 24, the construction being such that whenthe thread'parter 9 ismoved by engagement with the lay or a part thereonafter replenishing the filling, and after the shuttlejfeeler has beenmoved rearwardly to feeling position, the clamping member 19 will beclosed upon its cooperating clamping member 17 to securely clamp thethread leading from the cloth selva ge to the filling carrier which isto be ejected; and owing to the resiliency of the'spring 25 the clampingaction will be sufiiciently yielding to provide for differentthicknesses of the yarn engaged by the clamp. i

Extending from the shuttle feeler 2 is a supporting lug 30 carrying alaterally-extending rock shaft 31, Mounted on the rock shaft 31 is thethread catcher 32, the: hub portion 33 of which be secured to "the shaftby means of a set screw 3, 1. The thread catcher 32is providedat itsfree end with a hook 3 5" which is adapted to engage the thread leadingbetween'the cloth sel'vage and clamp, and to impulsively throw itfromthe machine under spring action; In" the present instance-of theinvention, the thread catcher 82 is under control of a spring36mounteduponthe rock shaft 31, one end of the spring being secured to thelug 30 at 37, and the other end of the spring at '38 being connected tothe thread catcher, the" construction being such that the spring 361willnormally'tend tomove the thread catcher 32 in a c'ontraclockwisedirection, and move ment of the catcher responsiveto thes'pring islimited by a suitable stop such,;for instance, as the pin 39 proectingfromvthe shuttle feeler or the fixed member of the the tensioning"arm '40fwliich; the shuttle feeler, parter and thread'catcher'move fromthe "front p 'rearwara position" after replenishment, is adapted to"'engagefa'ffixed jstop such as the rod 41 extenaing from {the sup- '1pg-fr hereifibefore described; the construc- Flgf. 1'. 20 parts carriedthereby are maintained in their normal from; position, f by means usualin the present invention; I called, the shuttle ffeeler as usual in thisf rearwardposition, position 'substanti'allyjndicated by tion beingsuchthat the threa catcher 32 will be "rocked "clockwise, wires-ease; that hill be above, the filling thread "a leading 5 from, the; cloth selvagetoconnected to the support 1 5 adjustably as for instance by thefjslottedarm 42; and the =c1amping, uv43 ,the construction being such that the"stop 4l mayb'e' adj ulsted to'sult' conditions ofuse.-"-Similarly,theoperating aria justably as by means o f theset lscr'ewi fl lc,
